Self-employment tax explained
- As a freelancer you pay both halves of FICA — employee (7.65%) + employer (7.65%) = 15.3% SE tax on 92.35% of net income (SS caps at $176,100).
- You can deduct half of SE tax from gross income before calculating income tax — this reduces your federal bill.
- This calculator uses the standard deduction. If you itemize, your actual income tax may be lower.
The safe-harbor rule
- Pay at least 100% of last year's tax (110% if AGI > $150k) to avoid underpayment penalties — even if your actual tax ends up higher.
- Or pay 90% of this year's tax. Whichever is smaller qualifies as safe harbor.
- Payments are due quarterly. Missing a due date means interest accrues from that date.
